# RFID vs NADCA Defects

The clearest difference is update cadence: NADCA Defects at every 2 days against RFID's every 4 weeks. RFID's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.4). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

RFID ships an update every 4 weeks, NADCA Defects every 2 days. The most recent releases landed on October 12, 2026 and October 7, 2026 respectively.
